Studio Lighting- Task One

Studio Lighting

Studio Lighting is very popular with photographers today, studio lighting is a complete set up of lighting to provide exact levels of light and shadow to create a desired effect within the final image. A full studio lighting set is made up of these pieces of equipment:

Backdrop: These can be any of the desired coloring however normally they are white or black.

Lights: These can be at a different wattage and can also be adjusted within the setting on the side on the box.

Soft boxes: These defuse the light, which in turns softens the shadows produced.

Snoot: This allows us to control the direction of the light beam, snoots can also isolate a subject when using flash.
Honey Comb: This narrows the light beam to a circle with soft edges.
Flash Adapter: These are used to as the flash guns go out exactly as you take the picture.

Umbrella: These also defuse the light source like the soft box does.

I have been learning a lot about studio lighting and how it works, Our eyes automatically Control the intensity in which we see by opening and closing it's iris, where as a camera uses three adjustments to control intensity. These are the aperture, shutter speed and the sensor speed ( IOS).
From what i have learnt in lesson and through research i can see that there are three characteristics of lighting  these are light intensity, light direction and light colour.

Light Intensity, Is the quality of the image, whether the light is perceived as hard or soft and how much light is hitting the object. Soft light is more overall lighting, using soft boxes or umbrellas, where as hard lighting is created using equipment such as a snoot to create a strong beam of light and strong shadows. We can manipulate the light by adjusting the aperture and shutter speeds within the settings. We could used use different filters or by using other sources of artificial lighting.
Light Directions, is the angle we use the lighting we can make something look very three dimensional as well as two dimensional and flat this depends on the object which we are photographing. We can use different equipment to create different textures and effects. We can control the way the light is reflected carefully to create the desired effect.
Light Colour, is to do with the colour balance white light has a colour cast, as humans our eyes automatically adjust to this where as on a camera sensor it does not. We can adjust the colour balance on the camera in the settings before we take an image, or afterwards. These include Florescent Lighting which is usually a green tinted colour, Incandescent Lighting which has a low colour temperature so this is an orange colouring. Candle light is similar although this is more of a deeper orange colour. The colour balance can also be adjusted in photoshop after the image has been taken.
